I uploaded two images to [Imgur][1] in the course of composing a question here. While _studying_ the screenshots, I discovered the answer to my question, but the images remain. Now that I don't need them, will they [automatically expire after three months][2]? Or is the [new Imgur pro account][3] going to keep around unlinked-images indefinitely?

I feel so wasteful.
